[目的]评价CT在胃癌孤立淋巴结转移中的诊断作用。[方法]回顾性分析胃癌孤立淋巴结转移患者75例临床资料。[结果]75例患者中,68例淋巴结转移位于胃周(N1)。另有7例患者淋巴结跳跃转移至N2～N3站,CT对孤立淋巴结转移胃癌患者T分期、N分期及M分期的准确率分别为73.3%、78.7%和90%。[结论]并非每个前哨淋巴结都位于胃周原发病灶附近。CT在孤立淋巴结转移胃癌患者TNM分期上的准确性较高。
[Objective] To evaluate the diagnostic value of CT in the diagnosis of isolated lymph node metastasis of gastric cancer. [Method] The clinical data of 75 patients with gastric cancer with isolated lymph node metastasis were analyzed retrospectively. [Result] Of the 75 patients, 68 cases of lymph node metastasis located in the stomach (N1). In addition, the lymph node metastases to N2 ~ N3 in 7 patients. The accuracy rates of T, N and M staging were 73.3%, 78.7% and 90% respectively in patients with lymph node metastasis of gastric cancer. [Conclusion] Not every sentinel lymph node is located in the vicinity of the primary gastric lesion. The accuracy of CT in TNM staging of patients with lymphatic metastasis of gastric cancer is high.
